I love Madoka! I've only watched the main series and movies, but I've had a blast going through the wiki pages that break down things about the witches from ... a game, I think? I keep meaning to watch other dark magical girl anime, just haven't found the time lately. x__x
Pokemon and Fire Emblem are the ones I've been playing since forever - but I have a soft spot for Assassin's Creed and loved Nier Automata. Currently playing Hades and FFXIV!
